If you don't want to use the metal can, use a spray paint can top. You can also put them on a canning jar lid, using it like an embroidery hoop. Pull the fabric over the stuffed spray paint can top & through the ring on the can. Then put in the lid & screw the whole thing back onto the jar & put sewing suppiles in the jar. I've seen these at craft fairs & they sell like crazy . You can make a smaller pin cusion for the jar by just making a small kind of pillow
